I have a folder with a bunch of photos taken by two different cameras, with one camera having been set to the wrong date. I managed to correct the EXIF date using Picasa (see photo.stackexchange), but apparently, it only adjusts the "Date Created" of the file, and not the "Date modified".

How can I make the "Date modified" (shown by default in the Finder) equal to the "Date Created" for a bunch of files?

I've looked in the touch terminal command, but couldn't find an answer there for my specific issue.
